Steven Chu on alleged CO2-induced bad weather: "Even if we don’t know all the gory details and the exact mechanisms, the trends are clear and ask us that we act"

I liked Chu’s overall take on climate change: He said, “I prefer to take a very epidemiological view of climate change, similar to the link between cigarette smoking and cancer. Even if we don’t know all the gory details and the exact mechanisms, the trends are clear and ask us that we act”.
